Open-source service runtime configured by agents via WebMCP
Mantle is an innovative open-source framework designed for developers and businesses seeking to streamline service development. It enables users to convert business rules into typed schemas, views, procedures, and HTTP/MCP triggers, all through a browser-based interface. The platform's WebMCP-native Builder allows for designing and verifying services visually, making it accessible to both technical and semi-technical users. Once the design phase is complete, a coding agent can finalize the service for self-hosting or deployment. With its open-source core and live live OSS and Builder tools, Mantle promotes flexibility and community-driven development. Additionally, Mantle Cloud, currently in Internal Beta, hints at an upcoming cloud-hosted offering that aims to simplify deployment and scaling. Its unique approach of combining visual service design with agent-assisted coding positions it as a compelling solution for rapid development, automation, and custom service creation.

Agents with their own computers, accounts, and budgets.
Solid is an innovative AI-driven platform that empowers autonomous agents to handle complex, long-term work tasks on behalf of individuals or teams. Unlike typical personal assistants, Solid agents operate independently by setting up their own physical machines, creating accounts, and managing budgets to execute workflows seamlessly. They interact with your apps via APIs or login credentials, building new solutions and resolving issues as they arise. This makes Solid ideal for organizations seeking to delegate substantial and ongoing projects without micromanagement, allowing users to focus on higher-level strategy while the agents handle operational details. Built for scalability and depth, Solid is suited for businesses that require reliable, autonomous support across various development and productivity tasks, offering a unique blend of automation, customization, and end-to-end management.
